The applet in question is a status display screen. I know it has
crashed because a) the data displayed is out of date, and b) it
doesn't respond to user input. Since it is a passive monitoring
system, there is no log written. No error is displayed, it just stops
updating properly. I guess what I was hoping for was that there might
be some indication I could get from the process list or the like that
I simply didn't know to look for, rather than an application-specific
check. Something along the lines of how you can check for a "zombie"
process by looking at the output of a ps. From the responses I have
gotten so far, however, this wouldn't appear to be the case. Thanks
anyway!

Is the applet the only interface to the system? Can you get the status
from the command line of the machine or only via a web based applet?
